BASH fetch?

Posted on 10th Jan 2025

I don't know why there are too many implementations that look like neofetch and why they are so complicated. I mean, i just saw one, using python and being tenths of files and hundreds lines of code. Why? Because of the ASCII logo?

Anyway... if you want a quick way to see a complete summary of system info, you can use inxi -b. Just that! If you don't have installed inxi, just sudo apt install inxi. That easy.

And if you don't want to install any other program/package, use the following script i made. It uses only BASH and Linux commands, no need to install anything. Feel free to customize it as you like.
